i have a stock drivetrain in my f 100 except for my new extreme torque torque converter from hughs...and my 36" tires......anyway i want to make the single ujoint at the front axle the absolute weekest link in my drivetrain...has anybody done this, and if so what size ujoint did you use?
Since the t-case has no differential, that still won't protect the rear axle from overtorqing. Also, be sure to install driveshaft hoops if you plan on breaking u-joints.
Originally posted by superswamper act like a fuse before i over torque anything else expensive...like axle shafts.
if i hear a loud pop, chance are i'm going to let off the throttle, which removes torque from the whole drivetrain.......besides how often do you break both ujoints at once? and according to what your saying i would break all the ujoints at once? on the other hand i do have a np 203 transfer case, which does have a differential in it, but i didn't mention that before, so no big deal there.

every rear axle shaft i've ever seen from the factory has a high yeild strenght then the front axle it is paired with. thats why you break ujoints in the front axleshafts more often then twisting the rear axle shafts. therefore if i put a fuse between the power source (xcase) and the weaker of the two axles (front) then i will save expensive axle parts and still have the rear wheels turning.
All good theory, but if you're doing stuff that can break driveline parts, how careful can you be to ALWAYS put more (or equal) load on the rear than front? I'd say it's fairly likely that you'll be in slop, spin all 4, and hit some hard stuff with the rear tires, and put ALL the torque on the rear driveline. I don't know ANYTHING about the 203, but is its diff lockable? Will you have it locked or open when you're wheeling? If it's always open, then the front driveline may be able to spin up fast and take some torque off the rear, but I doubt it.
If you think that possibility is remote, disregard all my comments.
